SPECIFICATION forming part of :Letters Patent No. 247,583, dated September 27, 1881, Application filed October 1i, 1880. (ModeL) To all whom it may concern:

Be it known that I, SILAs O. ScHoFIELD, a citizen of the United States, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Gorn'Shellers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification, and in which- Figure 1 is a side view of my improved cornsheller. Fig. 2 is a reverse side view thereof, and Fig. 3 is a sectional view of the same on line as as of Fig. 1. Fig. 4 is a detailed section on line y 2 of the same figure, and Fig. 5 is a plan view of the sheller.

This invention relates to improvements in corn-shellers, having for its object to increase the shelling capacity of the machine and to render the feed-aprons readilyremovable; and it consists in combining with a double shellerwheel and the two feed-wheels a two-part casing formed with the hopper halves arranged over the sheller-wheel, and a partition-piece secured between the two halves of the hopper part of said casing to form an independent hopper for eachside of the sheller-wheel; and, secondly, in combining with the hopper half having the open sockets, one on each side, the removable apron having studs or axes resting in said sockets of the hopper-half, and a bolt or rod coiled by a spring bearing against the removable nut of said rod or bolt and the hopper-half, substantially as hereinafter more fully set forth and claimed.

In carrying out my invention I employacircular case,A,composed of two parts or halves bolted together, and having suitably secured thereto, as at a, legs a, supportingit in an upright position With each half of the casing A, and at its upper end, is cast a hopper-half, A, bolted together and having their chambers separated by a partition, h, slid into vertical grooves h at the uniting parts of the hopperhalves A. The hopper=chambers are arranged one over each of the'two series of teeth on the sides of the shelling-wheel, as seen in Fig. 5,

to permit of the feeding and shelling simultaneously and at one operation two ears of corn.

D D are two aprons, with their lower ends provided with ribs '5, to effect the feeding of the corn rotatively to the shellin g-wheel when acted upon by the feed-wheels. The upper ends of the aprons are each provided with two studs,

f. which are supported in open eyes or sockets f in the upper edge of each hopper-half A, so as to permit of the ready removal of the aprons, when desired, for renewal. Each apron has at the same end, also, a rod or bolt, 9, which passes through its hopper-half, and is encircled between its removable not 9 and the hopper-half by a coiled spring,f, the objectof which is to hold the lower end of the apron yieldingly against the ear of corn.

Hung centrally in the case A, and upon a shaft, b, having the crank or handle I), is the sheller-wheel B, armed upon each side with a series of or numerous teeth, D to effect the shelling of the ears of corn passing down on .each side thereof, or two ears simultaneously and at one operation.

O O are the feed-wheels, arranged one in each of two halves of a supplemental case, A, cast with the two-part case A alongside of the hopper-halves A. These wheels are secured upon a shaft, (1, bearing in the sides of the case A and present their ribbed or milled peripheries to the hopper-chambers and the chambers of the case A, so as to affect the corn fed down into the hopper-chambers, and thus aid the feeding thereof to the chamber of the case A, where it is acted upon by the sheller-wheel B. These wheels 0 receive their motion through the pinion e, secured upon the shaft d and gearing with a sunken cogged surface in the periphery of the wheel B, as at I), Figs. 3 and 4. The lower edge of the partition h is adapted, as seenin Fig. 3, to prevent the getting of grains of corn, &c., into the sunken cogged surface of the wheel B.

It will be noticed that while the grains of corn will pass out of the chambers of the case A through a common spout, j, (see Figs. 1, 2, and 3,) the cobs will be discharged through each of two openin gs, j, made in opposite sides of the case A, as seen in .Figs. 1 and 2. A flange or ledge is provided at about It, Figs. 1 and 2, or just above each opening j, and with IOO in each chamber of the case A, to prevent the wheel and the two feed-wheels, of a two-part escape of the grains of corn thereat. case formed with the hopper-halves A A, ar- 15 Havingthus described myinvention, I claim ranged over the sheller-wheel, and a partition- Q and desire to secure by Letters Patentpiece secured between the two halves of the 5 1.
